Application filed August 23, 1925. Serial No. l3D,976.

This invention relates to heaters eepeci ally adapted tor use in heatingWater, although uotin any senee restricted to euch use.

Briefly Stated, an important object oi the invention is to pro fide aheater havingA novel, niieaue whereby the. heating' coil is mounted inthe oit heat t'roin the products: ot combustion ot either or both ol.Separate Source?l of heat euch as a gas burner or a lire of coale, wood,traeh or other combuee tible material.

A further and equally important object ol the invention ieto provide aheater ot the character epecilicd in which the droit F through theheater may be reverted flor operation under various conditioue.

@their objects and advantages; will be ep purent during the course ofthe tollowingij description.

In the accompanyingr drawings termine' a part of this application and inwhich like nuinerale are employed to designato like parte throughout thesaine,

Figure. l is a vertical sectional View through the improved heater;

d Figure 4 is a group perepective illustrating' several oit an annularoeriee o'li ribe einbodied in the invention;

Figure 5 ie a horizontal sectional View taken on line ol Figure l;

Figure 6 ie a horizontal Sectional View taken on line GWG oit Figure l.

ln the drawing the numeral 5 designates a shell or'heater casing'mounted upon the eeh pit or base portion (t, the base portion in turnbeing' eupported by leus; 7. .ln carrying out the invention a flue pipe8 ie attached to the upper portion of the cursing 5 andv coininunicateeeither with an annular chamber 9 or a retort tube l0. The retort 'tube10 is arranged centrally Within the casing '5 in spaced relation to theside Wall thereof and connnunication between the tube and the flue iscontrolled by ineane ot a combined Slide Valve and closure ll. Figure lclearly illustrates that when the Combined Slide valve and closure ie inwhat inigrht be said to be its open positiona it cuts ol'l directcommunication bet-Ween the retort tube and the iiue and et the sainetiine allows ot the admission of air to the retort tube by Way of anopening 14E. When the slide valve 1l is poeitiered ae shown iu Figure Q,there will be a down draft through the tube l0 and an up dra'lt throughthe annular chamber 9 will be permitted. G0

@n the other hand, when the combined Slide valve end closure l1 inclosed peeitiou, the admission oit air by wey oit the oylieuine lil cutoil and direct coinuiuuication between the tube l() :ud the liuc pipe 8G5 is eetahliehed. lt Will thus be eeen that the member ll 'functions aea nieane tor controlling` adinieeion oil nir to the tube 1.0 by aj-,f ofthe opening 14; and has a damper tor eontrollin25` connuunicationbetween the tube 70 l() and the due 8.

The retort tube l() is Surrounded by an annular series of ribs 18, thelower portioue ot' which are Seciuely held in place by a band 20 orother elutable -iaetening device and the upper portions of the ribe areengaged by Stops 22 by which the tube l0 is Supported. Vlttention nowdirected to Figure 4l: which illustrates that tho upper portions ot theribs 18 are provided with laterally projecting S0 houde or ehouldere 24;which act to uniformly Space the ribes about the retort tube.

The ribs 18 carry a plurality of radial pegs or lues 2G upon which theconyolutione of a coil 28 are mounted. It Will be ob- S5 served that theribs 18 may be position-ml Within the coil 8 and the lune 26 engagedwith tho conyolutioue of the coil preparatonr to the application ot' theretort tube 10, ln other worde, in originally assembling); the 9o partel@ 18 and 283 the lune 26 ot the ribs are engaged with the convolutionsof the coil and the ribs are then slipped onto the retort tube as aunit, after which they niay be locked in place by the band 20 and the 95retainers 22.

lVater may bc supplied to the coil by a pipe 30 and Water ina-y bedischarged by the pipe 3l, both of which iney have connection in theusual and Well known inanner with a suitably sized boiler 34.

Referring again to Figure l, it Will be seen that tie grate 16 iemounted on supports 36 and that an annular gas burner is also mountedupon the Supports outwardly of the grate. A gas; supply pipe may beconnected to the annular gas burner at one or more places, a suitablenumber of connections being; provided for this purpose.

In the operation ot the improved heater, fuel such as wood, trash orcoal is placed upon the L(grato l@ and ignited and in case the burner381 is operatingat the time combustion is taking place within the retorttube l07 a down draft in the tube l0 and an up draft through thechamber9 will be established. Of course, conninmication between the lowerportion of the retort tube 10 and the lower portion of the chamber 9 isby Way of the ash pit GQ To provide Afor I this vdown draft, however7 itis necessary to moveV the combined` closure .and damperyll to the open,position illustrated in Figure l. The heat from the fuel upon the grateand the gas burner will effectively heat the water in the coil.

`that the inovemento'.F the member ll is controlled by alnob 47 whichmay be easily grasped by the Alingers and which in addition tofunctioning as a knob acts as a stop,

A heater constructed in accordance with this invention Amay beeconomically manufact-tired and by reason of the la number of fuelswhich may be employed either alone or in conjunction Witli'gas, anextremely efiicientheater is provided.

Having thus described the i vention what is .claimed is:

'LA heatercomprising a casing, a grate in the bottom thereof, a tub-e insaid casing and spaced from the walls thereof, said casmemset) inghaving` al Itop provided with an air inlet and an outlet line1 a plateslidable over the top of said tube and closing` communication betweensaid tube and outlet flue in one position of die plate, said platebeing; formed to close communication between said tube and inlet andsin'iultaneously open communication between said .tube and outlet lluein another position of the plate, and means on said grate for supportingsaid tube.

2. A heater comprisinnr a cylindrical casing; having a closed topprovided with an outlet tlueandan air inlet, a `grate in tbe lower endthereof, an open. ended tube .supported on said grate and concentricwith said casing, water tubes surrounding said tube, and means at thetop of said tube for selectively changing said tube from an air inletdowndraft conduit to a llue outlet conduit troni the grate.

3. In a heater, a casina, a grate in tbc lower end thereof, an openended tube in the casinpr above said gratcwater coils surroundiiur saidtube, and aprigbts carried by said grate and forming; a common supportfor said tube, and water coils.

l. A water heater comprising a casing, a grate in the lower end thereof,a draft tube in saidcasiingz,` above the grate, a plurality ol' gratecarried uprights disposed around said tube and having' supporting`connection with the upper end of the tube, vertically spaced lugsextendingv laterally from said uprigihts between the tube and casing',and water coils supported on said lugs.

,In testimony whereof I allix my signa ture.
